"Ellsworth Kelly spent the years 1948–54 in Paris, and the period was formative for the young artist. He was introduced to European and American modernists, including Jean Arp and John Cage, both of whom had an enormous impact on Kelly’s development and the creation of the Study for 'Cité'. Cage and Arp encouraged Kelly to involve chance in his compositional arrangements, as Arp had done in Dadaist collages as early as 1916, and as Cage began to do in musical compositions in 1951."
